Subject: fix: handle BoringSSL and OpenSSL incompatibilities

This patch corrects for imcompatibilities between OpenSSL, which Node.js uses,
and BoringSSL which Electron uses via Chromium. Each incompatibility typically has
~2 paths forward:
* Upstream a shim or adapted implementation to BoringSSL
* Alter Node.js functionality to something which both libraries can handle.

Where possible, we should seek to make this patch as minimal as possible.
